Pregnancy in dogs will be very different from what humans experience quite a lot. A normal dog pregnancy is very short compared to that of a human, lasting only two months, which means that puppies will also develop really fast inside their mother. The gestation period is anywhere between 62 and 65 days long. Although the outside of the dog will surely change quite a lot, most changes will happen inside with and around the puppies. Let’s go over the gestation period, with a week-by-week timeline and the most important changes.

Keep in mind that you should always be on the lookout both during pregnancy and during whelping or delivery, so make sure you talk with your veterinarian and learn about the signs you should pay attention to. It’s always best to know that everything is normal and that you have nothing to worry about.

First Week

When a female dog is receptive to the male courting her, breeding will occur. This usually happens 10 to 20 days into the heat cycle. This is when her eggs are fertilized. An interesting fact is that a female dog is able to conceive puppies with multiple fathers within the same litter because canine ovulation results in several eggs.

The Second Week

As soon as the embryos are properly fertilized, they will have to travel in the horn part of the dog’s uterus which has a Y shape. They will then embed into the uterine lining.

The Third Week

This is when embryo development will occur. The dog’s energy levels and appetite will go through some noticeable changes.

The Fourth Week

The embryos growing inside the female dog can actually be felt by hand by the age of 25 to 28 days, but this manual exam should be done by a professional, so as to not hurt the little ones. You can also detect heartbeats with the help of an ultrasound by this point. The palpation of the puppies will then be prevented by the increasing fluid in the uterus within the coming days, and they will only be felt again very close to delivery. With the litter’s development, the mother’s appetite will also increase and the pace of increase will be pretty amazing.

These very high-demand times will require some impressive amounts of food, so make sure you have it readily available for your pet. To ensure that you also cover all of her nutritional needs, your pregnant and then nursing female dog should also receive dog food of the highest quality.

The Fifth Week

This is when the second stage of the pregnancy will begin for your female dog. This is when you should stop calling the puppies embryos and start referring to them as fetuses. These fetuses will start to increase drastically in weight, growing as much as 75% while their development continues and they start to grow their organs. The dog’s belly will also be larger. The pet might start to eat smaller meals but will need food more often.

The Seventh Week

The nipples of the female dog will release a cloudy fluid known as either colostrum or “first milk”, while the tissue around the breast will be swollen and the nipples themselves will get darker and more prominent. Some dogs also start to shed hair on their bellies. Some people say that this is also when they started to see the fetuses moving beneath the mother’s skin.

The Eighth Week

This is the week in which the puppies will start to position themselves in the birth canal, being fully developed and almost ready to come out. The dog might get anxious and will look for a quiet and safe place where to deliver the puppies, while the abdomen will seem to be in a continuous motion. Give her access to enough newspapers, towels, or even clean blankets to help her make her nest. A crate, a kiddie pool, or any other enclosure that gives her enough comfort and privacy would be the perfect place. Remember not to use things you might want to keep after the birth, because they will most likely be ruined when she goes into labor. You will also need to prepare a second bedding set to place inside the nest after the female has finished giving birth.

The Final Week

This is when the whelping begins. You should try to take the dog’s temperature at least once per day. Go for a rectal thermometer if possible and make sure the dog’s temperature is between 100.5 and 102 degrees Fahrenheit. You will notice that the temperature of the mother will go lower a few degrees just before giving birth. This is a sign that things are moving forward and the dog is very close to labor, which shouldn’t take more than 24 hours from that point. As soon as the dog will go into labor, make sure you give her space, but try to also keep her under observation.
